To all whom it may concern:

Be it known that I, HERBERT H. STEELE,

citizen of the United States, and resident of ing devices fortypewriting machines'and has for its main object to provide improveddevices of the class specified.

To the above. and other ends the invention consists in the features ofconstruction,

combinations of devices and arrangements of parts hereinafter describedand particularly pointed out in the claims.

My invention is applicable to various forms of writing machines althoughI have illustrated said invention as embodied in'a' Monarch typewritingmachine.

In the drawings, Figure 1 is a fragmentary side elevation partly insection of a Monarch typewriting machine embodying myinvention. Fig.2'1s-a fragmentaryrear elevationof the machine. Fig. 3..is ,a view,partly in sectio-ntaken on planes represented by the lines in F igy l.and looking directly downward as indicated by the anrows at said lines,said Fig; 3' showing the retarding devices mounted on the upper part ofthe machine. Fig. 4: is a vertical sectional view taken on planesrepresented by the line q y of Fig. 3.

A are omitted and partsbroken away.

strumentalities (not shown) are mounted on the main frame and the typebars when actuated are adapted to coeperate with the front face of arotary platen l mounted in a carrier or carriage comprising end bars 5and a rear bar or slide bars. The slide bar is grooved at its top andbottom faces to 00. operate with anti-friction balls 7 which alsocooperate with rooved guide rails 8 secured to standards 9 Xed to, andrising from the top plate 3. Arms 10 pivoted; on the carriage, support afeed rack 11 which normallymeshes with a feed pinion 12 fixed to thefront end of a horizontal shaft 13 which bears in a bracket 14 securedto the top plate. An escapement wheel 1;; is supported at the rear endof the shaft l hnd'cooperates with feed dogs 16 and '17 mounted at thetop of a dog rocker 18, said dog rocker being pivoted at 19 to a bracket'20 depending from the top plate and being connected by a link 21 with auniversal bar -(not shown operated by the key levers. A"'spring drum22'is connected by a strap 23 with a in 2.411epending from the slide bar6. aid spring drum, as-is well-known, tends constantly to draw thecarriage leftward over the top plate, the carriage movements in thisdirec tion', however, being ordinarily controlled by the operation ofthe escapement devices during the printing or spacing cf-the difierentcharacters in a line of writing.

The drawings, illustrate tabulatin mechanism. which comprises .arearwardy projecting stop arm 25 secured by screws 26 at the .rear of the slidebar 6. The stop 25 is adapted to cooperatewi-th one or more tabulatorstops27 adjustab-ly mounted on a toothed stop ,bar 28, said stop barbeingjoun' naled on arms'9 projecting rearward from Normally the steps27 are out of line with the stop 25but the stop bar 28-is adapted to beturned in its bear.

ings to bring said stops 27 in line with the stop 25 so that they mayooii iieratewhen the carriage is released. The 111621115 for soturningthe stop bar 28 comprise an arm. 29 secured near v downwardlyextending link 30, said link passing through ando ening in the top plateand at its lower en crank lever 3'1,'said' lever being pivoted-at 32 ona fixed bracket or armv 33. The other arm the bell crank lever 81 is'pivotally the right-hand. end thereof and ing connected to one arm of abell tent that even connected with a slide rod 34 which extends forwardand bears in an opening in the right-hand front corner-post 2, saidslide rod at its front end being provided with a tabulator key button orfinger spring 36 coiled around the upper portion of the link 30 operatesto maintain the stop bar 28 and its actuating devices in normalposition. When the tabulator key 35 is pushed rearward it operatesthrough the slide rod 34 and bell crank 31 to pull the link 30 downwardand turn the stop bar 28 so as to bring with the-tabulator stop 25 onthe carriage. Concurrently the carriage is released.

The releasing devices for the carriage operated by the tabulator key 25comprise a finger 37 secured to the link .30 and cooperative with onearm of a lever 38 pivoted at 89 'on a bracket 40 depending from the topplate. The other arm of the lever 38 is pivotally connected at 41 with alifting device or member 42, said lifting device near its upper endbeing bifurcated to cooperate with cut-outs in the sides of the bracket14. bifurcations ,of the device 42 are provided with lifting shoes whichare adapted to engage with the teeth of the rack 11 to separate it fromthe feed pinion 12 and thus release the carriage from its escapementdevices. In the present case however, I prefer to dispense with theselifting shoes and to provide the device 42 with a lateral ofi-set 42whichis formedwith a horizontal slot 42 which slot coiiperates with theretarding devices, 0 crating the latter to cause the release of thecarriage in a manner here inafter described at length.

The retarding devices devised by me and the stops 27 thereon into lineIn the usual constructionthe.

piece 35. A 1

about to be described make use of certain featuresof invention firstdisclosed in the patent to 'Felbel 898,635, granted September 19,1908.Said patent relates to a retarding mechanism which embodies means forinter rupting rality of times during a single run thereof from right toleft when released from the controlof the. escapement devices. Theserecurrent interruptions operate to diminish the momentum of the carriageto such an exafter long runs said carriage will be arrested by thetabulator stops without undue shock or noise. Theobstructing devicesbeing relatively weaker than the pulling force applied to the carriagewhen "it is released, theperiodical or intermittent interruptionsthereof will operate to nomentarily slacken the speed of the carriageand absorb'some of'the force with which otherwise the carriage wouldfinally strike;

" but will not effect a complete stoppage of place only w 65 saidcomplete stoppage taking the carriage,

hen the tabulator stops are brought into engagement.

the motion of the carriage a ph whole may It sometimes with lip-turnedhappens with a construction such as thatdisclosed in the said Felbelpatent that when the carriage is released for a free run one of theintermittent retarding devices will be engaged by or will be about to beengaged by the cotiperating retarding device so that at the start thecarriage may move sluggishly and an unnecessary amount of time beconsumed. My improved devices insure that the carriage after beingreleased may always move freely for some distance prior to the beginningof the effective operation of the retarding mechanism. a

The retarding devices casing or holder, the two parts whereof are showndetached in Figs. 9 and 10. One part 43 is in the nature of a box andthe other part 44 provides a cover therefor. The box or container 43comprises two connecting circular chambers 45 and 46. 'llhe outside ofthe larger chamber 45 is provided with a central boss 47 opposite towhich inside the chamber is a depression 48 having a central perforation49 (Figs. 3 and 9). The cover plate 44 is formed with a correspon ingboss 50, depression 51 and central opening 52. The smaller chamber 46 isprovided with an outside elongated boss 53 and a lower or shorter innerboss 54. The bosses 53 and 54 are formed foration 55, the'cover plate 44being formed with a corresponding perforation 56. -At the side of thelarger chamber 45 opposite to the smaller chamber the box-like container 43 is provided with an ehlargemen 57 which formed with a threadedhole 58 connected with the larger chamber and with two connecting holesor chambers 59 and 60 at right angles to each other. The cover plate 44is provided with a corresponding enlargement 61 formed with connectingholes 62 and 63 at right angles to each other. The edge of the container43 is provided with lugs 64 which are adapted to cooperate withcorresponding notches 65 in the cover with a central perare contained ina i tween the cover plate and the container when the two parts have beenfitted together. The two parts 43. and 44 are adapted to be heldtogetherby a headed an shouldered screw 66, said screw passing throughthe bearing openings 52 and 49 and serving as a pivot on which thecasing as a be oscillated; The pivot screw in a bracket comprising two66 is sup orted angled'p ates 67 and 68 (Figs. 3, 8 and The uprightbearing arms of the two plates I are spaced apart and'the plate 68'isseated on the plate 67, the two being secured to- J gether and to'thetop plate by a heade screw 69 behind the lower guide rail 8. The

horizontal arm of the plate 67 is provided fingers 67" which contactwith the rear vertical face of the lower guide rail and prevent thebracket as. a whole fitted in place prior to ing for the pivot screw 66,

' from turning on the screw 69 as a pivot.

The rear edge of the horizontal arm of the bracket arm 68 contacts withthe upturned fingers 67 so that relative turning movement between theangled plates 67 and 68 is also prevented; When the casing is mounted ona pivot screw 66 said caslng is confined between the upright arms of theangled plates 67 and 68, the bosses 47 and 50 contacting'with the innerfaces of the upright arms and preventing the two parts of-the casingfrom separating and also reventing movement of the casing as aw olelongitudinally of the pivot screw 66.

Prior to the mounting of the casing on its support and while the twoparts 43 and 44: are separate the devices contained in the two parts areassembled in place. A check or ball. 70 is placedin the hole and acorresponding check or ball in the hole 63. Companion balls 71 areplaced in the holes 59 and 62 and are held in contact with stop faces 59and 62 projecting into said holes by coiled pressure. springs 72 (Fig.3). These pressure springs cooperate with an adjustable slide orabutment 7 3 provided with plug-like portions 74 which are adapted tofit into the holes 59 and 62. The plugs 7e are formed with depressionsor seats 75 in which the ends of the springs 72 are received. A thumbscrew 76 asses through an opening in the .follower 3 and engages withthe threaded opening 58 in the member 4:3. The thumb screw is providedwith a shouldered portion 76 which cotiperates with the follower 73 toprevent movement of the follower endwise of the thumb screw and relativethereto. The construction is such that by turning the thumb screw in orout the pressure of the springs 72 will be regulated. It should beunderstood, however, that while the balls 70 and 71 and springs 72 maybe the assembling of the container 43 and cover 44, the slide orfollower 7 3 and thumb screw? 6 are not arranged in place until afterthe cover 44 is in place on the container. Prior to the assembling ofthe follower 73 and thumb screw 76 a rot-ary member or gear wheel. 77(Figs. ,3 and 4) is seated in the chamber The gear wheel 77 is providedwith oppositely dis posed hub portions 7 8 having a central openone ofthe hub portions being seated in the depression 48 and the other hubportion being adapted to be received in the depression 51 in the cover.The gear wheel is. formed with two opposite iy disposed arcuate slots75) each of which receives a steel ball. These balls are duplicates butfor convenience of reference will be given different numbers 80 and 80.The balls are prevented from falling out of the, slots when the partsare assembled by the walls of the container and coverplate. Each ball isnormally maintained in contact with one end of the associate slot by awire spring 81 which is coiled around one of the hub portions 78, oneend of each spring being secured in an opening in the hub andthe otherend extending into theassociate slot 79 and being bent to engage withthe ball 80 or 80*. The gear wheel 77, it will be noted, is in thenature of a ball container. A smaller gear wheel 82 is arranged in thechamber 46, said ear wheel meshing with the gear. wheel 7 7 he gearwheel 82 has a hub portion 83 which is perforated to receive a shaft 84which bears in the opening 55 in' the container. The hub 83 receives apin 85 which secures the gear wheel 82 and shaft 84; in fixed relation.When the cover plate is assembled the hub 83 is adapted to bear in thehole 56 therein. The shaft 84 rojects forward beyond the hub 83 and isenlarged as indicated at 84 providing a shoulder which.

abuts against the end 0f the hub. The enlarged portion has fixed to it atoothed wheel 86 which is adapted to cooperate withthe' teeth of therack 11. a

After the various devices above described, including the gear wheels 82and 77, the balls 80 and 80*, 70 and 71, the springs 48 and 72 and theshaft 84; have been arranged in the container, the cover thereof isputon and the follower 73 and thumb screw 7 6 assembled; Then the entirecasing and its contents are arranged between the uprights of the angledplates 67 and 68, after WlllCll the pivot screw 66 is screwed .in place.In mounting the casing on the machine the enlarged portion 84 of theshaft '84:, where said enlarged portion is exposed between the toothedwheel 86 and the hub 53, is entered in the slot way 42 in the liftingmember. The lifting member tends to maintain the retarding contrivancecomprising the casing and its contents in the position shown in Fig. 4.Said contri'vance is further provided with a restoring spring 87 whichas best shown in Fig. 8 engages at its free end with the top of the hub53, the opposite end of .the spring 87 being secured by a headed screw88 to the outer face of the angled plate 68. v

Supposing the parts to be initially in the relationships shown in Fig. 4in operation, the tabulator key is the tabulator stops and release thecarriage, the lifting member s2 is raised and the slotted extension 12thereof, cooperating with the enlargement on turn the retardingcontrivance on its pivot 66, raising the toothed wheel 86 intoengagement with the teeth of the rack 11. As the upward movement of thewheel 86 continues the rack 11 will be lifted until it disengages fromthe feed pinion 12, thus freeing the carriage, which will immediatelystart to move leftward under the pull of the main the shaft 34, willpushed into position leftward movement of the carriage causes thetoothed wheel 86 to' turn the gear wheel 82 which turns the gear wheel77 in the direction of the arrow in Fig. 4. If, as supposed, the partsstart initially from the po- 'sition illustrated in Fig. l, the wheel 77after it has turned a short distance will bring the ball 80 into contactwith the retarding or check devices or balls 70. These balls, as will bebest understood from a consideration of Fig. 3, may each have a slightbodily movement toward and away from the adjacent face of the wheel 77in the respective chambers 60 and 63. This movement is limited in onedirection by the adjacent face of the gear wheel and in the op ,0- sitedirection by the companion ball 1'. The hall 71 is under constantpressure from its spring 72 in a direction at right angles 29substantially to the direction of bodily movement of the ball 70. Theballs 71 are held from movement toward the associate ball 70 by therejections or sto s 59and '62; The balls 70, it will be-note are looseso "that they cannot impede the wheel 77 by contact with the wheelitself; but the balls 80 and 80 carried by said wheel are of suchdiameter that they cannot pass between the balls 70 until the latterhave been forced away from each other into contact with the associateballs 71, causing movement of said halls 71 and corresponding pressureof the springs 72. When, however, during the initial turning of the gearwheel 72, the ball 5 80 is first brought into contact with the balls 70,said halls 70 will not be forced apart for the reason that the springs72 are stronger than the springs 81. ,Gonsequently after the ball80'contacts with the balls 70 as shown in Fig. 5, said hall 80 willbeheld back by the balls 7 0 until the wheel 77 has turned fronrtheposition shown in Fig. 5 to that shown in Fig. 6. Comparing these twofigures it will be seen that the wheel Whas '5 advanced, causingrelative movement between the hall 80 and its slot 79so that said ballin Fig. 6 is in contact with the end of the slot 79, opposite from thatwith which it is normally maintained in contact. This relative movementbetween the hall 80and its. slot causes flexing oi the associate spring-81 beyond the normal. After the opposite end of the slot 79 has advancedfar enough to engage with the ball 80, how

ever, as shown in Fig. 6, further turning movement of the wheel 78 inthe direction of the arrow, will force theball 80 upward and willpressthe balls 70 apart to permit of this upward movement of the hall 80hecause the carriage main spring, of course, is stronger than thesprings 72. Pressure of the springs 7% is regulated by the regulatingdevicea'i't and 76 so as to cause a momentary checking or the speed oi?the carriage to an at entrant which is :liiound most advantageous inpractice. Up to this point, however, it be understood, the carriagemovement'has been substantially free and uninterrupted.

the checkihg balls 7 0 the associate spring 81 will operateon the ballSOto return it to its normal position against What may he termed theforward end ofthe associate slot 79. The parts at this time will, be inthe positions shown in Fig. 7. Considering said Fig. 7 it will be seenthat the wheel 7 7 after a further comparatively slight advancedmovement, will bring the ball 80 into engagement with the checkballs 70.Thereafter a further turning of the wheel will flex the spring 81,associated with the ball 80 and the'associate slot79 will pass said ball80 'until the opposite end of said slot engages with said ball andforces it past thecheck balls causing another momental? checking oi thecarriage. As soon as the all 80 passes the check balls it will be forcedhack to normal position in its slot by the spring 81. If the run'of'thecarriage is continued the operations above outlined may,- recur, thusaffording an intermittent or. periodic retardation of the carriage aftera free initial run thereof. I

When the carriage is arrested by the tabulator stops and the tabulatorkey is. released, the various parts will be restored to normal position,the retarding contrivance fluence of the member 42 and the restoringspring 87. When the retarding contrivance is disconnected from thecarriage loyvthe separation of the toothed wheel 86 from the rack 11itmay he that the checking balls 70 will not he in contact with eitherof the balls 80 or 80* in which case there will he no relative movementamong the various retarding. devices comprised in the retardingcontrivance after the contrivance is disconnected from the carriage.Examples of positions in which the check balls are'inoperative are shownin Figs. 4 and 7. It may be, however, that at the time of disconnectionof the retarding contrivancethe check balls and one of thecohperating'balls 80 or 80 will be in engagement and the associatespring 81-may he flexed; say, for example, in some such relation as thatshown, in 6. In this event after the disconnection of the retardingcontrivance the flexed spring 81 will operate to turn the gear backwardnoveinent of .the intermeshing gear 82 and associate parts until the endof the balhrengages with said ball, when the parts wlll come ,to a stop.From what has springs 81 are double acting. At times these springs mayact at their outer ends to advance their associate halls along the conAs soon as the ball 80 has been forced past' just been said it will benoted that the returning to normal position under the inits lit

At other times when the outer ends ofsaid springs are held from ad- From what has been said it will be appar.ent that the initial relation between the checking devices and thecoEiperat-ing balls; 80 and 80- will always besuch that a 'sub stantialfree and uninterrupted movement of l5 the carriage will take placeafterit has been released by the 'tabulator key prior to the momentarychecking or retardation of said carriage by the cooperationof thechecking balls and one or another of the balls 80 and- 80. It willfurthermore beapparent that during short runs of the carriage themovement of said carriage will be comparatively free so-that a minimumof time will be. consumed in such short run and' that duringlonger-runsof -the'carriage there will be one or more momentaryretardations occurring intermittently or periodically, the number ofsuch intermittent retardations=depending on the length of the run of thecarriage.

In the' modified construction shown Fig. 12 the main difference from thepreferred construction above described isrthat the pressure regulatingballs 71 are disrings72 engage directly with the checking alls 7 0.Owing to the proximity of the lower carriage rail it is not feasible toprovide an spring 7 2, the only adjustment for said spring being thatwhich it may receive indirectly from the adjustment of the oppositespring 7 2 which cooperates with an adjustable abutment or screw plug72. Furthermore, in the modified form it may sometimes happen thatinitially the check balls 72 may engage with the web or neck of the 77between the slots 7 9 in said wheel in which case there might be aslight checking of the carriage initially prior to the beginning of theinitial free run thereof.

Such checking if it occurs would, of course,

be slight and would depend for its degree on the tension of the spring72. Because of the superiority in these respects .of the first describedform, however, said first described form is the preferred one.

By my present inventionv it will be noted that-I combine means forintermittently decreasing the speed of the carriage during (either of 1.the carriage during its run, wvords,
